Description

Technical Field

[0001] This utility model relates to the field of metering and dispensing equipment, and in particular to a precise metering and dispensing equipment for PC sheet film raw materials. Background Technology

[0002] PC sheet film is widely used in fields such as architectural decoration, electronics, medical devices, and the automotive industry due to its excellent transparency, impact resistance, and dimensional stability. Precise metering and delivery of raw materials are crucial steps in the PC sheet film production process, directly affecting the product's molding quality, dimensional accuracy, and mechanical properties. This is of great significance for ensuring production continuity and reducing raw material waste. Currently, the raw material metering and dispensing equipment used in PC sheet film production has many shortcomings in practical applications. On the one hand, the raw material metering of existing equipment mostly relies on manual experience or simple mechanical structures for control. The adjustment of the dispensing amount lacks precise quantitative means, and the dispensing process is prone to significant deviations in the amount of raw material dispensed due to problems such as unstable material conveying speed and fixed dispensing mechanism volume. It is difficult to achieve accurate and even distribution of raw materials in different batches or with different formulas, which directly affects the consistency of subsequent products. On the other hand, the hopper and the device below the equipment are mostly fixedly connected or have complex disassembly and assembly structures. When it is necessary to clean the impurities in the hopper to avoid contaminating the raw materials, or to change to different specifications of hoppers according to production needs, the operation process is cumbersome and time-consuming. This not only reduces production efficiency, but may also affect the cleanliness of the raw materials due to untimely or incomplete cleaning, which in turn has an adverse effect on the quality of PC sheet film.

[0003] In response to this technical problem, this application proposes a precise metering and dispensing device for PC sheet film raw materials. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a precise metering and dispensing device for PC sheet film raw materials.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3An embodiment of this utility model provides a precise metering and dispensing device for PC sheet film raw materials, comprising a housing 1, two supports 2 fixedly connected inside the housing 1, a material dispensing shell 3 fixedly connected between the two supports 2, a material inlet 4 opened at the top of the material dispensing shell 3, a material dispensing plate 5 arranged inside the material dispensing shell 3, material dispensing bins 6 opened at the upper and lower ends of the material dispensing plate 5, a stop block 7 arranged inside the material dispensing plate 5, a sliding groove 8 opened on the side of the stop block 7, a sliding rod 10 arranged inside the sliding groove 8, a lifting plate 9 fixedly connected to the top of the sliding rod 10, and a docking interface 21 fixedly connected to the top of the housing 1, with a docking hole 14 opened at the top of the docking interface 21.

[0019] Specifically, during the PC sheet film production process, the raw material particles in the hopper 23 need to be processed by the distribution system before entering the production line. However, ordinary distribution devices cannot accurately measure and dispense the raw materials, affecting the subsequent film production process. Therefore, a box 1 is installed below the hopper 23. The raw materials enter the feed inlet 4 at the top of the distribution shell 3 through the discharge port 11 and the interface 21 inside the hopper 23, and then enter the distribution bin 6 opened on the distribution plate 5. The second motor 24 inside the 20 is connected to the rear side of the distribution plate 5. The rotation of the second motor 24 will drive the distribution plate 5 to rotate. After the raw material particles enter the distribution bin 6, they will be evenly divided into uniform weights due to the volume of the distribution bin 6. When the distribution plate 5 rotates, the raw material particles in the distribution bin 6 will rotate with the distribution plate 5 and eventually rotate to the position corresponding to the discharge port 22 on the lower side. The evenly divided raw material will fall at the discharge port 22 due to gravity and fall into the subsequent production line for further processing. During the rotation of the distribution plate 5, other places without distribution bins 6 will block the feed port 4 when they rotate past the position of the feed port 4, so that the raw material particles will not fall. Only when the distribution bin 6 on the distribution plate 5 passes the feed port 4 will the raw material in the feed port 4 fall into the distribution bin 6. Due to the volume of the distribution bin 6, the raw material particles are evenly divided into equal portions, and then rotated to the discharge port 22 for discharge.

[0020] Reference Figures 4-6 A limiting rod 13 is provided inside the docking hole 14. A limiting hole 17 is opened on the side of the limiting rod 13. A lever 16 is provided inside the limiting hole 17. A spring 15 is provided at one end of the lever 16. A feeding port 11 is fixedly connected to the top of the limiting rod 13. A protective shell 19 is provided at the top of the front bracket 2. A motor 25 is provided inside the protective shell 19. The driving end of the motor 25 is fixedly connected to the center of the front side of the abutment block 7. A protective shell 20 is fixedly connected to the top of the rear bracket 2. A motor 24 is provided inside the protective shell 20. The driving end of the motor 24 is fixedly connected to the center of the rear side of the distribution plate 5.

[0021] Specifically, during the material distribution process, the volume of the distribution bin 6 limits the amount of raw material particles per batch. To change the amount of material distributed each time by altering the volume of the distribution bin 6, the motor 25 inside the protective housing 19 is started after the device stops working. The protective housing 19 is fixedly connected to the distribution plate 5 and rotatably connected to the front support 2. The drive end of the motor 25 is fixedly connected to the abutment block 7. The motor 25 drives the abutment block 7 to rotate, which in turn causes the abutment block 7 to move the slide rod 10 along the slide groove 8. Since the slide groove 8 is an arc surface, the rotation of the abutment block 7 can control the raising and lowering of the slide rod 10, thereby driving the lifting plate 9 in the distribution bin 6. The internal lifting mechanism raises and lowers the material distribution plate 6, thereby changing its volume and the amount of material distributed. Motors 24 and 25 are located inside protective shells 20 and 19, respectively. Power supplies are installed inside both protective shells 20 and 19. The rotation of motor 25 will not affect its power supply. Both protective shells 19 and 20 can be opened to replace their internal power lines. When motor 24 starts rotating the material distribution plate 5, protective shells 19 and 25 rotate together with the material distribution plate 5. The rotation of the material distribution plate 5 will not cause the stop block 7 to rotate, thus changing the position of the lifting plate 9 and affecting the internal volume of the material distribution plate 6.

[0022] Reference Figure 1 and Figure 7 The outer wall of the lifting plate 9 is located inside the material distribution bin 6 to control the volume within the bin 6. The upper half of the sliding rod 10 is located inside the material distribution bin 6. The outer wall of the spring 15 is located inside the opening wall of the interface 21, and one side of the lever 16 is located outside the interface 21 to actuate the lever 16. A positioning block 12 is fixedly connected to the bottom of the discharge port 11. A positioning groove 18 is formed on the inner wall of the interface 21, and the outer wall of the positioning block 12 is located inside the positioning groove 18 to position the discharge port 11 when it mates with the interface 21. A hopper 23 is fixedly connected to the top of the discharge port 11, and a discharge port 22 is fixedly connected to the bottom of the housing 1.

[0023] Specifically, after the device has been working for a long time, contamination from raw material particles will leave impurities in the hopper 23, affecting subsequent production. Therefore, the hopper 23 needs to be cleaned. When there is no raw material in the hopper 23 and the device has stopped working, the lever 16 is moved and the spring 15 is compressed, causing the lever 16 to disengage from the limiting hole 17, releasing the restriction of the limiting rod 13 in the docking hole 14, and applying an upward force to the hopper 23, causing the hopper 23 to move upward. This causes the limiting rod 13 to disengage from the docking hole 14, and the positioning block 12 on the discharge port 11 slides upward along the positioning groove 18 on the docking interface 21 until it disengages from the positioning groove 18, completing the separation of the discharge port 11 from the docking interface 21, and realizing the separation of the material connected to the top of the discharge port 11. Disassembling hopper 23: After cleaning or replacing hopper 23, align the limiting hole 17 with the positioning groove 18 and the limiting rod 13 with the docking hole 14, then apply downward force to hopper 23, causing the limiting hole 17 to slide downward along the positioning groove 18. Insert the limiting rod 13 into the docking hole 14, and move the lever 16 to compress the spring 15. After the discharge port 11 is fully installed above the docking interface 21 and in the limiting position, release the lever 16 so that one end of the lever 16 is engaged in the limiting hole 17 under the rebound of the spring 15, thus completing the limiting lock between the discharge port 11 and the docking interface 21, thereby completing the quick installation between the discharge port 11 and the docking interface 21, and realizing the quick installation between hopper 23 and the lower device.

[0024] Working principle: During the material distribution process of PC sheet film production, raw material particles enter the feed inlet 4 at the top of the distribution shell 3 from inside the hopper 23 through the discharge port 11 and the docking port 21, and then fall into the distribution bin 6 opened on the distribution plate 5. The motor 24 inside the protective shell 20 is started. The drive end of the motor 24 is connected to the rear side of the distribution plate 5. The rotation of the motor 24 drives the distribution plate 5 to rotate. The raw material particles in the distribution bin 6 rotate together with the distribution plate 5, and finally rotate to the position corresponding to the discharge port 22 on the lower side. The evenly distributed raw material falls to the subsequent production line at the discharge port 22 due to gravity. During the rotation of the distribution plate 5, when other areas without distribution bins 6 pass the feed inlet 4, the feed inlet 4 is blocked, preventing the granular raw material from falling in. Only when the distribution bins 6 on the distribution plate 5 pass the feed inlet 4 will the raw material in the feed inlet 4 fall into the distribution bins 6. The volume of the distribution bins 6 divides the raw material granules into equal portions, and then the material is discharged at the discharge outlet 22 by rotation. If you want to change the volume of the distribution bins 6 to adjust the amount of material dispensed each time, you need to start the motor 25 inside the protective shell 19 after the device stops working. The protective shell 19 is fixedly connected to the distribution plate 5 and is rotatably connected to the front bracket 2. The drive end of the motor 25 is fixedly connected to the abutment block 7. The motor 25 drives the abutment block 7 to rotate, causing the abutment block 7 to drive the slide rod 10 to slide along the slide groove 8. Because the chute 8 is located on an arc surface, the rotation of the stop block 7 controls the lifting and lowering of the slide rod 10, thereby driving the lifting plate 9 to rise and fall inside the material distribution bin 6, changing the volume of the material distribution bin 6. Motor 24 and Motor 25 are located inside protective shells 20 and 19, respectively. Power supplies are installed inside both protective shells 20 and 19. Motor 25's power supply is not affected by rotation. Both protective shells 19 and 20 can be opened to replace the internal power supply. During the material distribution process, if it is necessary to disassemble the hopper 23 for cleaning or replacement, the lever 16 should be moved and the spring 15 compressed when there is no raw material in the hopper 23 and the device has stopped working. This will cause the lever 16 to disengage from the limiting hole 17 and release the restriction on the limiting rod 13 in the docking hole 14. The hopper 23 should be moved upward by applying upward force, and the limiting rod 13 should disengage upward from the docking hole 14. The positioning block 12 on the discharge port 11 should slide upward along the positioning groove 18 on the docking interface 21 until it disengages, thus completing the separation of the discharge port 11 from the docking interface 21 and completing the disassembly of the hopper 23. During installation, align the limiting hole 17 with the positioning groove 18 and the limiting rod 13 with the docking hole 14, then apply downward force to move the hopper 23 downward. The limiting hole 17 slides downward along the positioning groove 18, and the limiting rod 13 is inserted into the docking hole 14. Move the lever 16 to compress the spring 15. After the discharge port 11 is fully installed above the docking interface 21 to the limit position, release the lever 16. Under the rebound action of the spring 15, one end of the lever 16 is locked into the limiting hole 17, completing the limiting lock between the discharge port 11 and the docking interface 21, thus completing the quick installation of the hopper 23 and the lower device.
